I do tend to recommend people that are playing with their gender to try voice work. At minimum, its a cool party trick to make yourself sound androgynous, masc, or feminine. At best, it can make you feel a lot more comfortable and may make you better at singing. It also has low social impact (people can't see youre experimenting), you can just use it when you feel comfortable. Usually within a couple months of daily practice you can have some really noticeable gains.
